A Wiley mill was used to grind the dried leaf samples; the mill was cleaned between the grinding of each sample. Foliar N concentrations (percent dry matter (% DM)) were measured using the Kjeldahl method (Tan 1996), while foliar P concentrations (% DM) were determined with a UV-Visible spectrophotometer ( Corp) (Tan 1996).

A hammer mill is used to grind maize to the desired particle size prior to jet cooking, liquefaction, saccharification, and fermentation. Recently, this process is being referred to by the name "Dry Grind Ethanol" in order to prevent confusion. The third process referred to as maize dry milling is the process we are considering in this article.
